IPC: G11B5/66
Filed: 1986-04-23
Abstract: PURPOSE:To facilitate a control of magnetic anisotropy by impressing stress upon a ferromagnetic thin film and providing the thin film with magnetic anisotropy after forming such thin film. CONSTITUTION:When uniaxial stress sigma is impressed inside a film face of ferromagnetic thin film, uniaxial magnetic anisotropy  K is given in parallel with sigma. If a magnetostrictive constant of ferromagnetic thin film is lambdas,  K is shown by  =3lambdassigma/2. In addition, lambdas of Fe-Co-Si system alloy thin film which is vacuum deposited with a photoceram substrate is -0.5X10<-6> and its easy magnetizing direction is in parallel with a longitudinal direction and then its magnetic anisotropic constant K is shown by K=6.25X102erg/cm<3>. Subsequently, when a substrate 13 is bent by using a jig 11 and stress such as sigma=1.20X10<9>g/cm<3>is impressed upon the ferromagnetic thin film 14, the magnetic anisotropic constant is shown by K=-2.30X10<2>erg/cm<3>. Moreover, variation of magnetic anisotropy  K is -9.0X10<2>erg/cm<3> and is shown by K=-2.5X10<2>erg/cm<3>. Magnetic anisotropy, therefore, is given in an optional direction by impressing stress upon the ferromagnetic thin film after forming such ferromagnetic thin film and its degree can be controlled by that of stress sigma.

Title: Guide cart
Inventor: NONOGAMI TORAHIKO
IPC: A63B55/60
Filed: 1994-04-28
Abstract: PURPOSE:To safely travel along a rugged downward slope such as in a golf course by having a self-traveling body, a brake motor and a downward slope detection means, and equipping a main controller to intermittently operate a brake, upon detection of the downward slope. CONSTITUTION:A guide cart has a body 1 automatically traveling along a guide lane, a brake motor 36 for operating a brake to hold and lock rear wheels 4, an inclination sensor 67 as a downward slope detection means for detecting the downward slope of the travel road of the body 1. In addition, the cart is equipped with a main controller for intermittently operating a brake, when the inclination sensor 67 identifies the road as a downward slope. The main controller actuates the brake motor 36 and intermittently operates the brake, when the inclination sensor 67 detects a downward slope, thereby preventing the rear wheels 4 from slipping and reducing a brake wear. As a result, a drop in a braking force due to the overheat of a drum brake can be prevented.

Title: Gas collection safety valve
Inventor: IWAMOTO TOSHIO
IPC: F16K17/04
Filed: 1983-05-27
Abstract: PURPOSE:To collect gas by providing an exhaust gas collecting tube communicating with the gas collection system at the outlet of gas and preventing inner pressure rise due to abrupt pressure rise in the container. CONSTITUTION:A lower flange 7 is fixed to the container side while an upper flange 8 is fixed to the gas collection tube side. Normally it is contacted tightly against the seat 11 of valve through a spring 10 to seal the opening. Upon increase of gas pressure in the container, it will pass through a path 12 into a space 14 at the rear of a piston 13 to apply downward force onto a movable chip 9 caused by the difference of area between the stopper valve seat and piston. When the pressure in the container exceeds over the level set by said differential area and the spring 10 force, the movable chip 9 will move downward against the push-up force of spring to separate the stopper valve from the seat 11 thus to flow gas through the opening of container to the gas collection tube.

Title: Air conditioner and method for charging refrigerant for air conditioner
Inventor: KOBAYASHI ATSUSHI
IPC: F25B45/00
Filed: 1995-04-18
Abstract: PURPOSE: To facilitate a charging of refrigerant in an air conditioner and further prevent the refrigerant from being leaked out of the air conditioner by a method wherein a bypass pipe for bypassing a pressure reducing device is installed and this bypass pipe is closed after charging the refrigerant. CONSTITUTION: Under a state in which an outdoor machine 2 and an indoor machine 4 are not connected to each other, a charging of refrigerant to the outdoor machine 2 is carried out in such a way that a service valve 12 is closed and then a service valve 11 is opened and the charging is performed through this opened service valve 11. At this time, since the refrigerant and oil in the freezer bypass a capillary tube 9 acting as a resisting member, they are rapidly charged in an outdoor heat exchanger 8. Upon charging of a requisite amount of refrigerant and oil of the freezer, the service valve 11 is closed and after this operation, the bypass pipe 17 is collapsed by a jig. Since the bypass pipe 17 is collapsed with a strong force, the refrigerant is completely prevented from being flowed. Even if the refrigerant flows there, only a slight amount of it flows.  This is due to the fact that the collapsed bypass pipe 17 shows a quite higher resistance than the resistance of the capillary tube 9.

Title: Diamond film and formation thereof
Inventor: MIYANAGA SHOJI
IPC: C23C16/27
Filed: 1993-03-26
Abstract: PURPOSE:To form a diamond film excellent in adhesibility at a high speed by forming a silicide layer of Ni or Fe on a substrate and after that, heteroepitaxially growing the diamond film thereon. CONSTITUTION:After an amorphous silicon film is formed on the surface of the substrate made of an orientational silicide single crystal or the like by plasma CVD method, Ni or Fe is vapor deposited by electron beam heat- deposition method. Next, the silicide layer of Ni or Fe is formed by heating at about 550 deg.C in nitrogen atmosphere. Next, the diamond thin film is grown on the surface of the silicide layer of Ni or Fe with C generated by using a gaseous mixture of a C containing gas such as methanol with gaseous Hz as a raw material and decomposing methanol by micro-wave plasma CVD in magnetic field device. Since the silicide layer of Ni or Fe between the substrate and the diamond thin film acts as a catalyst, the diamond thin film excellent in adhesibility is grown at a high growing speed.

Abstract: PURPOSE:To facilitate and secure coupling by projecting a sectorial projection which is wider at its tip part than at its root on one flank and forming an insertion groove which is almost in the same shape with the projections and less in tilt angle than the projection in the other flank when coupling a light receiving/emitting element and an optical fiber with each other. CONSTITUTION:The sectorial projection 7 which is wider at the tip part than at the root part is formed on one flank of a receptacle used as an optical connector component and the insertion groove which is almost in the same shape with the projection 7 and less in tilt angle than it is formed in the other surface. Then, the projection and insertion groove 7 of a right and a left body are coupled by being slid to couple many single bodies with one another. Thus, the projection 7 is slid in and coupled with the insertion groove 8 and then the projection 7 deforms elastically to attain tight coupling.

Title: Voltage adjusting circuit
Inventor: ADORIANUSU YOHANESU MARIA FUAN
IPC: G05F1/10
Filed: 1990-04-10
Abstract: PURPOSE: To sufficiently suppress high frequency ripples by arranging a parallel stabilizer for generating an output voltage equal to the output voltage of a serial stabilizer parallelly to the output terminal of the serial stabilizer. CONSTITUTION: The parallel stabilizer PS1 is connected to the output terminal of the serial stabilizer, the parallel stabilizer PS2 corresponding to the parallel stabilizer PS1 at the output terminal is used and the reference voltage Us of the serial stabilizer is generated. In this case, the gain of an operational amplifier is reduced for high frequencies and the output impedance of the serial stabilizer is increased. Since the circuit PS1 same as a reference voltage circuit is arranged parallelly to a load ZL, the same voltage appears between both terminals of the circuit PS1 and thus, a current flowing through the circuit PS1 becomes the same as well regardless of the output impedance of the operational amplifier. Thus, high frequency interference affecting a stabilized power supply line is sufficiently suppressed.
